dr_madlabs griefing exploit

There is currently a bug in madlabs which can break the map and completely ruins your winning chances in the map.

On the last trap, after the 2 doors open in the corridor, if a player shoots the button at where the elevator is (with intention to activate it or not), instead of it preventing the bullets from activating it, what will happen is that because nobody is on the elevator, nobody is exempt from being teleported in the glass room at the end to wait for anyone. Instead it turns the end to a patience test between red team and hale to see who killbinds first.

This is easily abused by griefers and ruins a lot of moments when you could have easily won the match, only for someone to easily screw it up. It makes for a lot of annoying moments and for obvious reasons. The problem will only persist if the button isn't fixed.
